Cool thx for the comments. I am in a plain ol blue collar construction job, and I have seen the transition of hand tools to battery power over the last decade. So they are still charged on grid but it was interesting to watch more and more tools unplug over the years.
Also I made this post thinking about vehicles and the micro generation combustion engines that drive each individual car. But with a move to electric and battery power vehicles that puts the energy supplier on the grid where they weren't there before.
So I guess I'm also curious about the actual motors that run the micro generation systems. Are there any developments in hydrogen fuel cells, or new technologies in kinetic energy (wind and water)? Are there any other subs or online places to read and learn about this type of thing?
